Biden is a placeholder to attract the non-radical middle. If elected, he will be out of office shortly due to his "newly acknowledged" dementia. The VP pick is the real candidate.

Lots of women would be perfectly acceptable, just not the crypto-communists that the radical left wants. My disfavor for the women you name has absolutely nothing to do with the reasons you project. It matters not a man or woman, policies and political beliefs matter.

Contrary to feminist belief, it's not all about gender.
